[FEA] Add Multiple Signal Classification (MUSIC) support to radartools

[awthomp]

MUSIC is a commonly used algorithm for direction finding and frequency estimation.

Monson Hayes in _Statistical Signal Processing and Modeling _ provides the following MATLAB algorithm for MUSIC:

function Px = music(x, p, M)
  R = covar(x, M);
  [v, d] = eig(R);
  [y, i] = sort(diag(d));
  Px = 0;
  for j=1:M-p:
    Px=Px + abs(fft(v(:,i(j)), 1024));
    end;
  Px = -20*log10(Px);
  end;

This repository implemented MUSIC and other array signal processing libraries https://github.com/petotamas/pyArgus.
The library is tested with real world!
